Speaking in general terms, how would you call things (assets) that need to be bought or created in order to be able to complete a task (tools, materials, devices, etc.), when you want to ephasize that it has physical form, as opposed to things like knowledge, information, skills, etc.
What if I say something like:
"material means" or "substantive instruments"?
“[my word] which are used to implement flood protection measures (barriers, etc.) are provided mainly by the maintenance or purchasing department.”
